The emergence of pathogens represents substantial threats to public health, livestock, domesticated animals, and biodiversity. How wild populations respond to emerging pathogens has generated a lot of interest in the last two decades. With the recent advent of high-throughput sequencing technologies it is now possible to develop large transcriptomic resources for non-model organisms, hence allowing new research avenues on the immune responses of hosts from a large taxonomic spectra. We here focused on a wild...

Data from: Parsing the life-shortening effects of dietary protein: effects of individual amino acids

Sara Arganda, Sofia Bouchebti, Sepideh Bazazi, Sophie Le Hesran, Camille Puga, Gérard Latil, Stephen J. Simpson & Audrey Dussutour
High-protein diets shorten lifespan in many organisms. Is it because protein digestion is energetically costly or because the final products (the amino acids) are harmful? To answer this question while circumventing the life-history trade-off between reproduction and longevity, we fed sterile ant workers on diets based on whole proteins or free amino acids. We found that (i) free amino acids shortened lifespan even more than proteins; (ii) the higher the amino acid-to-carbohydrate ratio, the shorter...

Data from: Circadian periodicity in space use by ungulates of temperate regions: how much, when, and why?

Guillaume Peron, Antoine Duparc, Mathieu Garel, Pascal Marchand, Nicolas Morellet, Sonia Said & Anne Loison
1. When they visit and revisit specific areas, animals may reveal what they need from their home range and how they acquire information. The temporal dimension of such movement recursions, i.e., periodicity, is however rarely studied, yet potentially bears a species, population, or individual-specific signature. 2. A recent method allows estimating the contribution of periodic patterns to the variance in a movement path. We applied it to 709 individuals from 5 ungulate species, looking for...

Data from: Resource composition mediates the effects of intraspecific variability in nutrient recycling on ecosystem processes

Charlotte Evangelista, Antoine Lecerf, J. Robert Britton & Julien Cucherousset
Despite the growing evidence for individual variation in trophic niche within populations, its potential indirect effects on ecosystem processes remains poorly understood. In particular, few studies have investigated how intraspecific trophic variability can modulate the effects of consumers on ecosystems through potential changes in nutrient excretion rates. Here, we first quantified the level of intraspecific trophic variability in 11 wild populations of the omnivorous fish Lepomis gibbosus. Outputs from stomach content and stable isotope analyses...

Data from: Combining GWAS and RNA-seq approaches for detection of the causal mutation for hereditary junctional epidermolysis bullosa in sheep

Aroa Suárez-Vega, Beatriz Gutiérrez-Gil, Julio Benavides, Valentín Perez, Gwenola Tosser-Klopp, Christophe Klopp, Stephen J. Keennel & Juan José Arranz
In this study, we demonstrate the use of a genome-wide association mapping together with RNA-seq in a reduced number of samples, as an efficient approach to detect the causal mutation for a Mendelian disease. Junctional epidermolysis bullosa is a recessive genodermatosis that manifests with neonatal mechanical fragility of the skin, blistering confined to the lamina lucida of the basement membrane and severe alteration of the hemidesmosomal junctions. In Spanish Churra sheep, junctional epidermolysis bullosa (JEB)...

Data from: Arthropod distribution in a tropical rainforest: tackling a four dimensional puzzle

Yves Basset, Lukas Cizek, Philippe Cuénoud, Raphael K. Didham, Vojtech Novotny, Frode Ødegaard, Tomas Roslin, Alexey K. Tishechkin, Jürgen Schmidl, Neville N. Winchester, David W. Roubik, Henri-Pierre Aberlenc, Johannes Bail, Héctor Barrios, Jonathan R. Bridle, Gabriela Castaño-Meneses, Bruno Corbara, Gianfranco Curletti, Wesley Duarte Da Rocha, Domir De Bakker, Jacques H.C. Delabie, Alain Dejean, Laura L. Fagan, Andreas Floren, Roger L. Kitching … & Jacques H. C. Delabie
Quantifying the spatio-temporal distribution of arthropods in tropical rainforests represents a first step towards scrutinizing the global distribution of biodiversity on Earth. To date most studies have focused on narrow taxonomic groups or lack a design that allows partitioning of the components of diversity. Here, we consider an exceptionally large dataset (113,952 individuals representing 5,858 species), obtained from the San Lorenzo forest in Panama, where the phylogenetic breadth of arthropod taxa was surveyed using 14...

Data from: Regression commonality analyses on hierarchical genetic distances.

Jérôme G. Prunier, Marc Colyn, Xavier Legendre & Marie-Christine Flamand
Landscape genetics is emerging as an important way of supporting decision-making in landscape management, in response to the deterioration of matrix permeability due to habitat loss and fragmentation. In line with unremitting methodological developments in landscape genetics, a new analytical procedure was recently proposed as a way of evaluating the effects of landscape gradients on genetic structures. This procedure is based on the computation of inter-individual hierarchical genetic distances (HGD), a metric of genetic differentiation...

Data from: Parallel and non-parallel behavioural evolution in response to parasitism and predation in Trinidadian guppies

Lisa Jacquin, Simon M. Reader, Amandine Boniface, Jaquelynn Mateluna, Iola Patalas, Felipe Pérez-Jvostov & Andrew P. Hendry
Natural enemies such as predators and parasites are known to shape intra-specific variability of behaviour and personality in natural populations, yet several key questions remain: (1) What is the relative importance of predation versus parasitism in shaping intra-specific variation of behaviour across generations? (2) What are the contributions of genetic and plastic effects to this behavioural divergence? And (3) to what extent are responses to predation and parasitism repeatable across independent evolutionary lineages? We addressed...

Data from: Tracking marine mammals in 3D using electronic tag data

Christophe Laplanche, Tiago A. Marques & Len Thomas
1. Information about at-depth behaviour of marine mammals is fundamental yet very hard to obtain from direct visual observation. Animal-borne multisensor electronic tags provide a unique window of observation into such behaviours. 2. Electronic tag sensors allow the estimation of the animal's 3-dimensional (3D) orientation, depth and speed. Using tag flow noise level to provide an estimate of animal speed, we extend existing approaches of 3D track reconstruction by allowing the direction of movement to...

Data from: Developing reduced SNP assays from whole-genome sequence data to estimate introgression in an organism with complex genetic patterns, the Iberian honeybee (Apis mellifera iberiensis)

Dora Henriques, Melanie Parejo, Alain Vignal, David Wragg, Andreas Wallberg, Matthew Webster, M. Alice Pinto & Matthew T. Webster
The most important managed pollinator, the honeybee (Apis mellifera L.), has been subject to a growing number of threats. In Western Europe one such threat is large-scale introductions of commercial strains (C-lineage ancestry), which is leading to introgressive hybridization and even the local extinction of native honeybee populations (M-lineage ancestry). Here, we developed reduced assays of highly informative SNPs from 176 whole genomes to estimate C-lineage introgression in the most diverse and evolutionarily complex subspecies...

Data from: The influence of early-life allocation to antlers on male performance during adulthood: evidence from contrasted populations of a large herbivore

Jean-François Lemaître, Louise Cheynel, Frederic Douhard, Gilles Bourgoin, François Débias, Hubert Ferté, Emmanuelle Gilot-Fromont, Sylvia Pardonnet, Maryline Pellerin, Benjamin Rey, Cécile Vanpé, A.J. Mark Hewison, Jean-Michel Gaillard & A. J. Mark Hewison
1. To secure mating opportunities, males often develop and maintain conspicuous traits that are involved in intra-sexual and/or inter-sexual competition. While current models of sexual selection rely on the assumption that producing such traits is costly, quantifying the cost of allocating to secondary sexual traits remains challenging. 2. According to the principle of allocation, high energy allocation to growth or sexual traits in males should lead to reduced energy allocation to the maintenance of cellular...

Vasohibin1, a new mouse cardiomyocyte IRES trans-acting factor that regulates translation in early hypoxia

Anne-Catherine Prats, Fransky Hantelys, Anne-Claire Godet, Florian David, Florence Tatin, Edith Renaud-Gabardos, Françoise Pujol, Leila H Diallo, Isabelle Ader, Laetitia Ligat, Anthony K Henras, Yasufumi Sato, Angelo Parini, Eric Lacazette & Barbara Garmy-Susini
Hypoxia, a major inducer of angiogenesis, triggers major changes in gene expression at the transcriptional level. Furthermore, under hypoxia, global protein synthesis is blocked while internal ribosome entry sites (IRES) allow specific mRNAs to be translated. Here, we report the transcriptome and translatome signatures of (lymph)angiogenic genes in hypoxic HL-1 mouse cardiomyocytes: most genes are induced at the translatome level, including all IRES-containing mRNAs. Our data reveal activation of (lymph)angiogenic factor mRNA IRESs in early...

Data from: A critical analysis of the potential for EU Common Agricultural Policy measures to support wild pollinators on farmland

Lorna Cole, David Kleijn, Lynn Dicks, Jane Stout, Simon Potts, Matthias Albrecht, Mario Balzan, Ignasi Bartomeus, Penelope Bebeli, Danilo Bevk, Jacobus Biesmeijer, Róbert Chlebo, Anželika Dautartė, Nikolaos Emmanouil, Chris Hartfield, John Holland, Andrea Holzschuh, Nieke Knoben, Anikó Kovács-Hostyánszki, Yael Mandelik, Heleni Panou, Robert Paxton, Theodora Petanidou, Miguel Pinheiro De Carvalho, … & Jeroen Scheper
1. Agricultural intensification and associated loss of high-quality habitats are key drivers of insect pollinator declines. With the aim of decreasing the environmental impact of agriculture, the 2014 EU Common Agricultural Policy (CAP) defined a set of habitat and landscape features (Ecological Focus Areas: EFAs) farmers could select from as a requirement to receive basic farm payments. To inform the post-2020 CAP, we performed a European-scale evaluation to determine how different EFA options vary in...

Tree diversity is key for promoting the diversity and abundance of forest‐associated taxa in Europe

Eric Allan, Evy Ampoorter, Luc Barbaro, Hervé Jactel, Lander Baeten, Johanna Boberg, Monique Carnol, Bastien Castagneyrol, Yohan Charbonnier, Seid Muhie Dawud, Marc Deconchat, Pallieter De Smedt, Hans De Wandeler, Virginie Guyot, Stephan Hättenschwiler, François‐Xavier Joly, Julia Koricheva, Harriet Milligan, Bart Muys, Diem Nguyen, Sophia Ratcliffe, Karsten Raulund‐Rasmussen, Michael Scherer‐Lorenzen, Fons Plas, J. Van Keer … & Lars Vesterdal
Plant diversity is an important driver of diversity at other trophic levels, suggesting that cascading extinctions could reduce overall biodiversity. Most evidence for positive effects of plant diversity comes from grasslands. Despite the fact that forests are hotspots of biodiversity, the importance of tree diversity, in particular its relative importance compared to other management related factors, in affecting forest‐associated taxa is not well known. To address this, we used data from 183 plots, located in...

Disentangling the roles of bottom-up and top-down drivers in the trade-off between food acquisition and safety in prey with multiple predators

Olivier Pays, Pierrick Blanchard, Simon Chamaillé-Jammes, Marion Valeix, Andrew Loveridge, David Macdonald, Stéphanie Périquet, Esther Van Der Meer, Patrick Duncan, Godfrey Mtare & Herve Fritz
1. Prey face a trade-off between acquiring food and avoiding predation, but food availability, and therefore its effect, is rarely measured in field studies investigating non-lethal effects of predation. The main aim of this study is to investigate the role of the presence of predators in the functional adjustments of feeding parameters with patch quality in a medium-size herbivore. 2. In Hwange National Park (Zimbabwe), we set up an experiment by manipulating, over two years,...

In situ resistance, not immigration, supports invertebrate community resilience to drought intensification in a Neotropical ecosystem

Camille Bonhomme, Régis Céréghino, Jean-François Carrias, Arthur Compin, Bruno Corbara, Vincent E.J. Jassey, Joséphine Leflaive, Vinicius F. Farjalla, Nicholas A. C. Marino, Thibaut Rota, Diane S. Srivastava & Céline Leroy
While future climate scenarios predict declines in precipitations in many regions of the world, little is known of the mechanisms underlying community resilience to prolonged dry seasons, especially in “naïve” Neotropical rainforests. Predictions of community resilience to intensifying drought are complicated by the fact that the underlying mechanisms are mediated by species’ tolerance and resistance traits, as well as rescue through dispersal from source patches. We examined the contribution of in situ tolerance-resistance and immigration...

Data from: Nucleolar sub-compartments in motion during rRNA synthesis inhibition: contraction of nucleolar condensed chromatin and gathering of fibrillar centers are concomitant

Pavel Tchelidze, Aassif Benassarou, Hervé Kaplan, Marie-Françoise O'Donohue, Laurent Lucas, Christine Terryn, Levan Rusishvili, Giorgi Mosidze, Nathalie Lalun, Dominique Ploton & Marie-Françoise O’Donohue
The nucleolus produces the large polycistronic transcript (47S precursor) containing the 18S, 5.8S and 28S rRNA sequences and hosts most of the nuclear steps of pre-rRNA processing. Among numerous components it contains condensed chromatin and active rRNA genes which adopt a more accessible conformation. For this reason, it is a paradigm of chromosome territory organization. Active rRNA genes are clustered within several fibrillar centers (FCs), in which they are maintained in an open configuration by...

Data from: The functional syndrome: linking individual trait variability to ecosystem functioning

Allan Raffard, Antoine Lecerf, Julien Cote, Mathieu Buoro, Remy Lassus & Julien Cucherousset
Phenotypic variability is increasingly assessed through functional response and effect traits, which provide a mechanistic framework for investigating how an organism responds to varying ecological factors and how these responses affect ecosystem functioning. Covariation between response and effect traits has been poorly examined at the intraspecific level, thus hampering progress in understanding how phenotypic variability alters the role of organisms in ecosystems. Using a multi-trait approach and a nine-month longitudinal monitoring of individual red-swamp crayfish...
